CARRIAGE-SPRING.`

Specification of Letters Patent No. 8,152,` dated June 10, 1851.

To all 'whom t may concern.' i

Be it. known that I, CHAUNCEY H. GUARD, of Brownville, in the county ofi Jefferson and State of New York, have invented certain new and useful Improvements in Buggies, &c.; and I do hereby declare that the following is a full and exact description thereof, reference being had to the accompanying drawings, making a part of this specification, Figure l, being a side view of a buggy, and Fig. 2, a top view of the forward axle of the said buggy, with 'the bolster and broken sections of the springs connected thereto.

The same letters refer to corresponding parts in both figures.

The nature of my invention consists in the rst place, in the combination of spring perches B, B, with the springs A, A, which support the carriage or buggy body in such a manner that the said spring perches, at the same time that they serve to connect the foremost to the hindmost axle, also serve to regulate the action of the carriage supporting springs and prevent them from being strained or injured. And in the second place, my invention conslsts in the combination of the bolster D, with the forward axle- F, through the medium of the fifth wheel C, andthe double brace e, as represented in the drawings, and hereinafter set forth. The spring perches B, B, are placed immediately below the semielliptic supporting springs A, A, and are secured to the hindmost axle G, and tothe bolster D, by the same fastenings 7L, 71,', as shown in the drawings. The spring perches B, B, have an upward curvature, but do not curve to the same extent and heightas do the supporting springs A, A, which produces an open space between lthe two-save at their extremities.

When sufficient weight `is placed in the vehicle to produce a change in the curvature of the supporting springs, the extremities of thevsaid springs will be forced outward, which will cause a tension strain to be exerted upon the spring perches. The apex of the supporting springs can be made to descend until the spring perches are drawn perfectly straight, when the said perches will act as cords to the then positions ofthe` arched supporting springs and prevent them from yielding farther, which will add greatly to the strength and security of the said supporting springs, and also to their easy and uniform action.

rlhe bolster D, is confined to the forward i axle F, through the medium'of the grooved fifth wheel C, `the double brace c, and the bolt i, in the following manner; to wit: the fifth wheel C, rests in a recess in the top of the axle; the bolster D, rests upon the fifth upon the fifth wheel, but cannot be oscil-` lated thereon by the.action of the supporting springs or the spring perches which are y connected thereto.

Having thus fully described my improvements in buggies, `&c., what I claim as my invention andldesire to secure by Letters Patent, is-

The connecting of the axles of wheeled Vehicles by means of curved spring perches which are combined with the supporting springs of the vehiclethat have a greater degree of curvature than themselves-substantially inthe manner and for the purpose as herein set forth.

The above specification of my improvements in carriages signed this 3rd day of April, 1851. i
